ABSTRACT: Phenotypic and genotypic coefficients of variation, heritability, genetic advance and path coefficient for 13 traits were estimated in 27 advance lines of Pearl millet (Pennisetum typhoides L). High estimates of phenotypic and genotypic coefficients, heritability and genetic advance determined the scope for improvising harvest index, grain yield per plant, 1000 grain weight, number of effective tillers per plant, length and girth of panicle, through simple selection. However, there was little variability and scope for selection for days to maturity and 50% flowering in the material. Path analysis further indicated the importance of plant height, harvest index, 1000 grain weight, length of panicle, girth of panicle, leaf length and with, as these characters showed highest direct effect on grain yield.
